python的进程，线程、协程

python进程的实现

#coding:utf-8
from multiprocessing import Process
import time


def run(name):
    print('%s is running' % name)
    time.sleep(3)
    print('%s finished his run' % name)


if __name__ == '__main__':
    p = Process(target=run, args=('XWenXiang',))  # 创建一个进程对象
    p.start()  # 告诉操作系统创建一个新的进程
    print('父进程')

python线程的实现

python协程实现的代码

(协程是在线程的基础上进一步切换)

#coding:utf-8
import asyncio

async def hello():
    print("Hello")
    await asyncio.sleep(3)  # 模拟耗时操作
    print("World")

asyncio.run(hello())
